plspage: Set page parameters 

DESCRIPTION:

    Sets the page configuration (optional).  Not all parameters are
    recognized by all drivers and the interpretation is device-dependent.
    The X-window driver uses the length and offset parameters to determine
    the window size and location.  This routine, if used, must be called
    before initializing PLplot.
